Open the access door on the right side of the machine. The battery disconnect switch is located in the engine compartment.
Disconnect Switch ON - To activate the electrical system, insert the key for the battery disconnect switch and turn the key clockwise. The battery disconnect switch must be turned to the ON position before you start the engine.
Disconnect Switch OFF - To deactivate the electrical system, turn the key for the battery disconnect switch counterclockwise to the OFF position. The battery disconnect switch and the engine start switch perform different functions. To disable the entire electrical system, turn off the battery disconnect switch. When you only turn off the engine start switch, the battery remains connected to the electrical system.Turn the battery disconnect switch to the OFF position and remove the key when you service the electrical system or any other machine components and when the machine will not be used for an extended period of a month or more. This will prevent drainage of the battery.
Never move the battery disconnect switch to the OFF position while the engine is operating. Serious damage to the electrical system could result.
